Abstract (en)
The utility model relates to alternative energy. The present wind turbine includes a symmetrical housing, which tapers from a lower part to an upper part and has a hemispherical fairing mounted thereabove, and lateral ribs which are vertically fastened on the housing and on which is fastened an annular fairing with a convex outer surface, a multi-bladed wind impeller being rigidly fastened inside of said annular fairing on a vertical electric generator shaft, wherein the hemispherical fairing has an aerodynamic annular baffle fastened in the lower part thereof, and the hemispherical fairing is configured to have a diameter greater than the diameter of the annular fairing with a convex outer surface. The utility model is aimed at increasing the speed of an air stream passing through the plane of rotation of a wind impeller while simultaneously preventing meteorological precipitation and foreign objects from entering the plane of rotation of the wind impeller.
